DENTIFRICE.

No Drawing. I

To all whom it may mm.-

Be it known that I, LEO MANDELSTAMM,' a citizen of the United States, residing at New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in Dentifric'es,

. of which the following is a specification.

My invention relates to improvements in dentifrices and more particularly to dentifrices containing radium.

An object of my invention is to provide a dentifrice which is harmless'to the humanorganism but which is antiseptic and germicidal innature and at the same time stimulating to the gums.

It is very easily possible to provide a dentifrice with the proper abrasive 'or cleansing ingredients but such a dentifrice in most cases has no germicidal action.

It is also easily possible to provide a dentifrice having a strong ermici'dal and antiseptic action but the di culty in these cases is that such action is likely to have a detrimental effect upon the delicate tissues of the mouth.

I believe the improved dentifrice which I have devised combines the beneficial effects of the well-known dentifrices on the market. which have no medicinal action, together with the antiseptic and germicidal properties which are necessary in'a'dentifrice of most approved type.

My improved dentifrice is produced in the following manner:

As the base of my following v2 ounces powdered chalk, 1 ounce powdered chloride of potash, 1 ounce of sugar, ouncewater, ounce powdered 40 castile soap, 10 drops carbolic acid, 10 drops oil of cloves, 10 drops oil of cinnamon.

I claim no originality for the above in,-

dentifrice, I use the gredients as these are all ingredients well" vanadium chloride of the above strength.

Application filed October 28, 1924. Serial No. 746,417.

known in dentifrices, but I have selected the ingredients in the above proportions as compatible with the additional substances which I propose to use in my improved dentifrice.

To 4 ouncesof the above mixtureas a base I add 4 centimeters of a 22% solution of vanadium chloride and 10 centimeters '50" of glycerin containing of a microgram of radium chloride. I find that radium chloride in a glycerin solution is stable and can be successfully used in combination with I have found by clinical tests that a dentifrice of the above composition whilst having the normal cleansing effect of the ordinary dentifrice, also provides by reason of its vanadium content a strong but harm-' less germicidal and antiseptic action. I The effect of the radium chloride present is to act as an invigorator and stimulant for the healthy and unhealthy gum tissue.

Having fully described-the composition of my improved dentifrice, what I claim is 1. Ina dentifrice, the combination of neutral abrasive materials, a vanadium salt and a radium salt. I 1

2. In a dentifrice, the combination ofneu- 7o tral cleansing and abrasive materials, and a vanadium salt. 3. In a dentifrice, the combination; of chalk, essential oils, water, a vanadium salt and a radium salt.

4. In a dentifrice, the. combination of chalk, oilof cloves, oil of cinnamon, 2. vanadium salt and a radium salt.

5. In a dentifrice, the combination of I glycerin,-neutral cleansing and abrasive materials and small amounts of vanadium and radium salts. I

In testimony whereof I hereunto affix. my signature.
